%description
Functions for MultiDimensional Feature Selection (MDFS): calculating
multidimensional information gains, scoring variables, finding important
variables, plotting selection results. This package includes an optional
CUDA implementation that speeds up information gain calculation using
NVIDIA GPGPUs. R. Piliszek et al. (2019) <doi:10.32614/RJ-2019-019>.
